Subject: the format string of printf to print audit status is wrong
Date: Thu, 31 Jul 2008 13:07:48 +0800 [thread overview]
Message-ID: <489148A4.3050807@cn.fujitsu.com> (raw)
Hello Steve,
all audit status's type is __u32, so '%u' should be used
in format string of printf rather than '%d', otherwise the
value outputted to user will be wraparound.
For example:
# auditctl -r 4294967295
AUDIT_STATUS: enabled=1 flag=1 pid=8999 rate_limit=-1 backlog_limit=320
lost=2241 backlog=0
but it should be
# auditctl -r 4294967295
AUDIT_STATUS: enabled=1 flag=1 pid=8999 rate_limit=4294967295
backlog_limit=320 lost=2270 backlog=0
This is the patch. Can you apply it?
